摘要：
A drive system for a pump includes a first housing defining an internal pressure chamber, a working fluid disposed within and charging the internal pressure chamber, a second housing disposed within the first housing, a solenoid disposed within the second housing, a reciprocating member slidably disposed within the solenoid, a pull housing integral with a first end of the reciprocating member, the pull housing defining a pull chamber, a pull disposed within the pull chamber, and a fluid displacement member coupled to the pull.
